Apple and Mozilla on Tuesday both released updates to address multiple security vulnerabilities in their respective web browsers, Safari and Firefox. Apple's updates fix two flaws in Safari for Mac and three in Safari for Windows, according to a support article. The flaws could allow arbitrary code execution or an unexpected crash. Meanwhile, Mozilla issued updates for Firefox, the SeaMonkey application suite and the Thunderbird email client to resolve 14 vulnerabilities, 10 of which are labeled "critical." The bugs could allow an attacker to execute arbitrary code, obtain sensitive information, launch cross-site scripting attacks, or cause a denial-of-service condition. Users are advised to update to Firefox 3.6.9, SeaMonkey 2.0.7 and Thunderbird 3.1.3. — AM
